Indicates that the platform dependency was not found during activation of the ClickOnce deployment, and that the deployment will not run.
Assembly: System.Deployment (in System.Deployment.dll)
This exception is thrown when there is a mismatch between the platform requested in the deployment manifest and the platform on which ClickOnce is attempting to run the application. "Platform", in this context, can refer to the operating system, the installed versions of the common language runtime, or a previously installed assembly. For example, if the ClickOnce application asserts that it requires Windows XP, and the user is attempting to run the application on Windows 2000, this exception will occur.
